7mm Winchester Short Magnum Rifle Cartridge

Abbreviated Name: 270 WSM

TECHNICAL INFORMATION:

All of the WSM cartridges are based on the 404 Jeffery non-belted magnum cartridge, and have been shortened to fit a short action. The 7mm WSM has a case shoulder location that is slightly longer than its 30 caliber parent or 270 caliber child. This is to prevent the 7mm from being chambered in either of the other two WSM's. Our favorite powders are 4350 and RL19.
